The camera head is detachably connected to an eyepiece unit of a plurality of types of endoscopes inserted into a subject, the camera head including an imaging unit that captures a subject image received from an endoscope among the plurality of types of endoscopes that is connected to the eyepiece. The detection unit that detects a size of the subject image in the captured image on the basis of a luminance signal of each pixel in the captured image obtained by the imaging unit. The distortion correction processing unit that corrects an optical distortion of the captured image depending on sizes of a plurality of different subject images.

A video signal generating apparatus is disclosed which includes: a camera configured to generate a video signal; an operating device configured to operate at least either the camera or an apparatus configured to receive the video signal; a text data generating device configured to generate text data including a meaningful term in response to the operation performed on the operating device; and a text data inserting device configured to insert the text data generated by the text data generating device into the video signal in a corresponding manner.

Endoscopes having a tip section with viewing elements coupled to a CMOS image sensor and/or a CCD image sensor for transforming light captured by the viewing element into digital and/or analog signals are described. A main connector is coupled with the tip section for transmitting the signals to a main control unit of the endoscope. The main connector includes a pad for transmitting digital signals provided by the CMOS image sensor to a push pin probe in a receptacle of the main control unit. The main connector also include another interface for transmitting analog signals to the main control unit.

An image relaying device comprises a shaft, an objective lens at a distal end of the shaft, an optically transparent window region in a proximal end region of the image relaying device, an optical system in the shaft, the optical system relaying an image produced by the objective lens to the proximal end region in a way that the relayed image can be captured through the window region. The optical system's optical axis at the window region is orthogonal or substantially orthogonal to the optical system's optical axis in the shaft. An optical instrument makes use of a plurality of these image relaying devices and a corresponding plurality of image sensors where the optical path length of each image relaying device may be independently adjusted to correct for optical inconsistencies in the elements of each relaying device.

An endoscope apparatus provided in the invention has forced disposability of a cannula by the means and techniques put in place so that the parts in contact with organic tissues or the detection of container extraction cannot be used, re-used, or if re-used, in a way that aligns with their operating limits. Activation of the cannula is detected and traced using sensors or wireless intercommunication devices so that when a certain time lapses or a certain number of activations after the first activation of the cannula, a limited usage means disables the cannula in mechanical or electrical way to ensure forced disposability of the cannula.

An endoscope inspection system includes an endoscope inspection apparatus and a package that packages an endoscope. The endoscope inspection apparatus includes a communication connector and a processor. The processor drives an image pickup device circuit of the endoscope to receive a response signal, determines based on the response signal whether a status of an image pickup device circuit is good or poor, and notifies a result of determination. The package includes a first fixing shape portion that fixes the packaged endoscope connector and a first fitting shape portion fitted with the communication connector such that an endoscope-side communication terminal of the fixed endoscope connector is electrically connected to an inspection apparatus-side communication terminal of the communication connector.

An endoscope apparatus including a connector included in an endoscope and connected to an endoscope connection portion of a video processor, a fluid feeding apparatus including a tube configured to transmit fluid to the endoscope, a connection detector configured to detect a connection state of the tube with the connector of the endoscope, a control unit configured to detect an ON/OFF state of a power source of the fluid feeding apparatus, determine an abnormality exists when the connection detector detects that the tube is in a disconnected state with the connector of the endoscope and the power source of the fluid feeding apparatus is detected to be in an ON state, and output a notification of the determined abnormality, and a display configured to display the notification of the abnormality outputted by the control unit.

Provided is an endoscope system capable of preventing a detection target from being overlooked in the case of using an automatic detection function for the detection target, and an operation method for the endoscope system. A comparison processing unit 74 performs comparison processing of comparing first-diagnosis identification information acquired at a first diagnosis with second-diagnosis identification information acquired at a second diagnosis that is different from the first diagnosis. A notification control unit 76 performs, if a determination is made that there is a difference in a detection target between the first diagnosis and the second diagnosis as a result of the comparison processing, control to make a notification about an oversight of the detection target.

Presented are systems and methods for the accurate acquisition of medical measurement data of a body part of patient. To assist in acquiring accurate medical measurement data, an automated diagnostic and treatment system provides instructions to the patient to allow the patient to precisely position a medical instrument in proximity to a target spot of a body part of patient. Based on a series of images acquired from a kiosk camera and an instrument camera, these instructions are generated. Subsequent images from instrument camera are analyzed by automated diagnostic and treatment system utilizing a database and deep convolution neural network (DCNN) to obtain measured medical data. An error threshold measurement by the automated diagnostic and treatment system may determine the accuracy of the instrument positioning and the medical measured data. The measured medical data may be communicated to a physician.

A method for preparing and/or caring for a medical or dental instrument is defined in that the instrument jointly with a connection adapter is first connected to a first preparation and/or care device and subsequently to a second preparation and/or care device. Furthermore, a coupling device is described which is configured to connect a preparation and/or care device for a medical or dental instrument to a connection adapter. A plug-in coupling arrangement and a system are also disclosed.
